IENCL HOLDER OR CASE.

Application led April l2, 1921.

To @ZZ ywlw/nt if; ymay conce/M1y Be it known that l, Pnnor Leolmnn Brioronn, a subject ot the King of IGreat Britain and l eland, residing` at London, county ot llfliddlesex, England, have invented new and useiiul Improvements iny l encil Holders or Cases, ot which the following is a specication.

This inventioii relates to that kind oit iencil-holder or pencil-case known Everpointed or ot similar name.

ln certain or these holders or cases, at present constructed, there .is always great risk et breaking` the lead when fittingon the outer sheath or case, as the lead inerely restingg` by its butt end on the propelling' rod projects, tor practically its entire lengtl'i` beyond such rod, and it is While the lead is in this position that the outer sheath or casing` has to be litted on. This i'ittingl on has to be done With greatnicety, so as to avoid risk of breaking' the lead, which is slender and very trail. Furthermore, in pencil-holders or cases ot this kind, the lead is seldoin or never steady, and therefore by nf'obblinp', when in use, occasions much inconvenience to the user oll the instrument.

Non', the object ot this invention is so to construct these instruments as to avoid all risk ot breakingthe lead when fitting' on the outer sheath or tubular cover, and also to render the lead, when inserted in the holder, and in use, tree liroin wobble, the construction being such that the outer sheath or cover can. be litted on When the lead is entirely retracted. or nearly so, Within the tube carrying;` the propelling` action And in order that the invention may be clearly understoml I will now describe it Llullv With reteronce to the accompouring,` drauings uf'hereinlFig. l is an elevation et the pencilliolder in its corn alete orin.

Fig; il is a longitudinal section ol3 the saine.

F'g. is a transverse section taken on the .line of Fig. 2 but to a larger scale.

Fig. 4l is a detached View. in longitudinal section, ot one et .the tubes ol' the holder, that hereinafter called grip tube.

Fig, 5 is also a detached view. in longitudinal section.. olf the double slotted tube in which the propeller Works.

Serial No. 460,614.

Y); and this tube is slotted at @l (see Fin, el)

lto torni a spring so that it can be adjusted,

when necessary, to take up Wear. The tube o, is turther {itted With the usual pencil-case action comprising' a stationary longitudinally slotted tube d, a longitudinally Inovable threaded nut c2, to which the propeller c is attached, and an internally threaded revoluble tube f for operating the propeller c to advance the lead, and said tube is counected by suitable means as by soldering` to the stationary tube Z or the action, by ineans of' a tube e of lesser clitiriietei'.

rlhe usual and Well-known internally threaded tube of the action, along" which the propeller c travels, is extended to jorin the reservoir barrel g (for spare leads) Awhich is provided with a screuv capy b2, and this barrel is also provided with a inount .7i (athough a knurled ring` may be employed) lined to. the barrel g for operating` the action to propel or advance the lead t' which is inserted in the conductor or `:guide-tube c1 lixed to the stationary tube (l, which is soldered in to the connecting' tube e, and which lead is retracted into the body ot the holder prior to hitting on the outer sheath b. rhe propeller is, as usual, fitted into the tube (Z, slotted at d1 on both its sides and through which slots the screw or nut c2, on the inner end of the propeller, projects to engage the threads ot the tube f.

1Where a Very quick action desired to p repel the lead, the usual and Well-known spirally slotted tube would be substituted tor the lthreaded tube The said tubes being thus arranged, the stationary tube ci, and the connecting tube c project beyond the grip tube o, as shown in Fig. and torni a series of steps, the purpose of which is hereinafter mentioned.

The outer sheathior tubular cover is, according to iny invention, made in a single piece with the body ot the holder, and is tapered oil' at its outer end7 as shown, to torni the point 1, and so avoid the use ice oit' a separate piece or screwed-on point, as is now the case and which is liable to work loose and Alall oli". This point 1 is 'further fashioned internally with a series or stepped recesses b3, b4, `725, forming a bearing or bearings for the projecting portions of the stationary tube and connecting tube e, the final recess Zi", at the point end, being formed, internally, with straight walls 210 for the purpose of tightly enclosing the lead and ensuring For it a steady and central guide, so preventing wobble.

ln' order to insert a lead into thc holder, the outer sheath b, is withdrawn, and the mount )t (or it may be the knurled ring) is then rotated to the left, so retiring the propeller' rod c. T he lead is then inserted into the conducting or guide tube n c1, and the sheath is replaced. To propel the lead, the mount it is rotated to the right, so causing they internally threaded tube j' of the action to revolve, andthe nut c2 to advance to propel the lead outwards, the lead, as propelled, passing through the conducting or guide tubes c1.

Havingnow described my invention what I claim and desire to secure by Letters Patent, is

l. ln a pencil holder or case of the kind referred to, a detachable sheath and means ior safely holding a lead While Vfitting on the sheath, said means comprising a conductor or guide tube to receive the lead, outer and fixed tubes iitting over said guide tube comprising` With a plunger and a plunger head the action of the holder, and. a slotted grip tube enclosing said tubes, all ott said members being enclosed in said sheath.

2. In a pencihholder or case of the kind mentioned, a slotted tube forming a grip tube, a stationary tube Within said grip tube, a pencil-case action associated with said stationary tube, and a detachable outer sheath or cover tube fitting over the grip tube, the slot in the grip tube permitting a spring to take up Wear.

3. In a pencil holder or case of the class specified, the combination of a slotted tube forming a grip tube, a pencil case action having a stationary tube secured Within said grip tube, a rotatable internally threaded tube, a reservoir barrel for spare leads formed as an extension of the internally threaded tube, a lead propelling device which has a member cooperating with the threaded tube, a mount on said barrel lor advancing the said propeller and its lead, anda detachable outer sheath fitting over the slotted grip tube and held in close contact therewith by friction.

i. In a pencil-holder or case of the kind mentioned, the combination of a slotted grip tube, a stationary tube associated with other elements of a pencil-case action, and a connecting tube Within the sta-y tionary tube, the said stationary and connecting tubes projecting beyond the grip7 tube and forming a series of external steps, and a sheath having internal steps cooperating with said external steps.

5. ln a pencil-holder or case of the hind mentioned, a detachable sheath or outer tubular cover having its body portion and its point formed in a single piece, action mechanism one element of which comprises stationary and connecting tubesl externally stepped, said point being fashioned internally with a series of stepped recesses corresponding With the steps formed by the stationary and connecting tubes of the action, and adapted to constitute a bearing or bearings for said tubes.

In Witness whereof, I have hereunto signed my name in the presence of two sub- BEDFORD.
